Kalibraatio (Calibration) refers to the process of adjusting and verifying the accuracy of measuring instruments or systems by comparing them against a known standard. This ensures that devices provide precise and reliable measurements, which is crucial in industries like manufacturing, healthcare, electronics, and scientific research.

1. Accuracy & Reliability – Ensures instruments provide correct measurements.
2. Regulatory Compliance – Meets quality and safety standards.
3. Cost Efficiency – Reduces waste and rework due to measurement errors.
4. Safety – Critical in medical, aerospace, and automotive industries.
5. Longevity of Equipment – Regular calibration extends device lifespan.

1. Mechanical Calibration – Measures pressure, force, torque, and vibration.
2. Electrical Calibration – Tests voltage, current, resistance, and frequency.
3. Temperature Calibration – Verifies thermometers, ovens, and sensors.
4. Dimensional Calibration – Ensures micrometers, calipers, and rulers are accurate.
5. Chemical Calibration – Used in pH meters, gas detectors, and spectrometers.

1. Preparation – Select reference standards and check environmental conditions.
2. Execution – Compare device measurements against the standard.
3. Adjustment – Fine-tune the instrument if deviations are found.
4. Documentation – Record calibration results for audits and traceability.
5. Certification – Issue a calibration certificate if the device meets standards.

Calibration frequency depends on usage, manufacturer recommendations, and industry standards. High-precision instruments may need calibration monthly, while others may require yearly checks.

• Calibration adjusts instruments to match a known standard.
• Validation ensures a system meets regulatory and operational requirements.

Basic calibrations can be done in-house with proper tools, but critical instruments should be handled by accredited labs for compliance.

If a device fails, it may need repair, adjustment, or replacement. Past measurements may need reevaluation if accuracy is compromised.

Traceability ensures calibration standards are linked to national or international reference standards (e.g., NIST, ISO), providing credibility.

Yes, extreme temperatures can impact measurements. Calibration should be done in controlled environments unless the device is designed for harsh conditions.

No, calibration checks accuracy, while maintenance involves cleaning, repairs, and part replacements to keep equipment functional.

• Medical (lab equipment, surgical tools)
• Aerospace (sensors, navigation systems)
• Automotive (safety testing, emissions)
• Pharmaceuticals (quality control)
• Energy (power grid monitoring)

An accredited lab follows international standards (ISO/IEC 17025) and undergoes audits to ensure reliable calibration services.

Look for:

• Accreditation (ISO 17025)
• Experience in your industry
• Turnaround time and pricing
• Customer reviews and certifications

Kalibraatio is essential for ensuring precision, safety, and compliance across industries. Regular calibration prevents errors, reduces costs, and maintains high-quality standards. Whether performed in-house or by accredited labs, proper calibration practices are critical for operational success.
